Supported Features
==================

The mimxrt1015_evk board configuration supports the hardware features listed
below.  For additional features not yet supported, please also refer to the
:ref:`mimxrt1064_evk` , which is the superset board in NXP's i.MX RT10xx family.
NXP prioritizes enabling the superset board with NXP's Full Platform Support for
Zephyr.  Therefore, the mimxrt1064_evk board may have additional features
already supported, which can also be re-used on this mimxrt1015_evk board:

System Clock
============

The MIMXRT1015 SoC is configured to use the 32 KHz low frequency oscillator on
the board as a source for the GPT timer to generate a system clock.

Serial Port
===========

The MIMXRT1015 SoC has four UARTs. ``LPUART1`` is configured for the console,
and the remaining are not used.

Programming and Debugging
*************************

Build and flash applications as usual (see :ref:`build_an_application` and
:ref:`application_run` for more details).

Configuring a Debug Probe
=========================

A debug probe is used for both flashing and debugging the board. This board is
configured by default to use the :ref:`opensda-daplink-onboard-debug-probe`,
however the :ref:`pyocd-debug-host-tools` do not yet support programming the
external flashes on this board so you must reconfigure the board for one of the
following debug probes instead.

:ref:`jlink-external-debug-probe`
-------------------------------------------

Install the :ref:`jlink-debug-host-tools` and make sure they are in your search
path.

Attach a J-Link 10-pin connector to J55. Check that jumpers J47 and J48 are
**off** (they are on by default when boards ship from the factory) to ensure
SWD signals are disconnected from the OpenSDA microcontroller.

Configuring a Console
=====================

Regardless of your choice in debug probe, we will use the OpenSDA
microcontroller as a usb-to-serial adapter for the serial console. Check that
jumpers J45 and J46 are **on** (they are on by default when boards ship from
the factory) to connect UART signals to the OpenSDA microcontroller.

Connect a USB cable from your PC to J41.

Use the following settings with your serial terminal of choice (minicom, putty,
etc.):

- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1

Flashing
========

Here is an example for the :ref:`hello_world` application.

.. zephyr-app-commands::
    :zephyr-app: samples/hello_world
    :board: mimxrt1015_evk
    :goals: flash

Open a serial terminal, reset the board (press the SW9 button), and you should
see the following message in the terminal:

.. code-block:: console

    ***** Booting Zephyr OS v1.14.0-rc1-1297-g312d75f2459e *****
    Hello World! mimxrt1015_evk
